Refer to Example 5.4. The joint density of Y1, the proportion of the capacity of the tank that is stocked at the beginning of the week, and Y2, the proportion of the capacity sold during the week, is given by f (y1, y2) = 3y1, 0 y2 y1 1, 0, elsewhere. a Find F(1/2, 1/3) = P(Y1 1/2, Y2 1/3). b Find P(Y2 Y1/2), the probability that the amount sold is less than half the amount purchased.
